It almost sounds like your IC is restricting your flow so much
it's backing up on the turbo side slowing down the exhaust side letting it heat up to much. That could also explain the more consistant boost modulation with the N75 valve. I would be very careful with this condition until you can get it properly explained. I would begin by checking for blockage in the IC or the lines...

But every time you shift gears the turbo has to fill up the air space again since it went into the
engine or out the bpv. So the turbo has to work harder to fill that larger space again. The problem I am having is that the faster I drive the temp on the other side of the FMIC where the boost sensor is will drop and the higher the rpm the more the turbo has to supply boost. So if you take in account that the turbo is working harder to fill that larger space and that I still have the stock cat on the car. Then add the lower temps at the other side of the FMIC which will drop the pressure lower then what the stock IC. The stock K03 cant keep up with the requested boost at the higher rpms. I am going to test to see if the high flow or a straight pipe will help with this problem.

So I guess you think more hp is better then more tq for everyday driving.
The 1psi drop will not make that much of a difference. But the lower temp will let the ecu run more adv timing which will give you alot more tq.

I agree...
I'm running the Abt FMIC and my temps did not get that much higher--maybe 5 degrees (and I'm in San Diego too). I'm no mechanical genius, but to make you turbo run harder and hotter seems to defeat the purpose of the FMIC. I thought an FMIC would extend the life of your engine, not burn it out.
But then again, maybe you drive harder than I do.

Is it? I don't know...
I haven't seen the EVO unit--though I'd like to! I can now understand that the turbo must spool up more to fill the FMIC, but does EVO market the unit as safe for a KO3?
You have a T-28 which I assume is bigger (like I said earlier, I'm no mechanical genius), but how big a turbo do I have to get in order to bring the temps down? What was the EVO unit built for? Thanks!
